Abstract

Embodiments are directed to infusion devices, systems, and methods to detect a capacity of a collapsible fluid reservoir of an infusion cartridge and/or a volume of a fluid disposed in the collapsible fluid reservoir or some other parameters of the infusion cartridge, and setting corresponding therapeutic parameters of an infusion device. Embodiments may include, obtaining data on the volume of fluid in the collapsible fluid reservoir, analyzing the obtained data to determine the setting of therapeutic parameters, and setting one or more therapeutic parameters of an infusion device.

Claims

1. A method for detecting a capacity of a collapsible fluid reservoir in an infusion cartridge and setting therapeutic parameters of a portable infusion pump with a processor of the portable infusion pump, comprising:

obtaining from the infusion cartridge, with the processor, data on a capacity of the collapsible fluid reservoir when the infusion cartridge is loaded into the portable infusion pump;

analyzing, with the processor, the obtained data on the capacity of the collapsible fluid reservoir to determine the capacity of the collapsible fluid reservoir; and

determining and setting with the processor, prior to delivering therapy using the infusion cartridge, one or more therapeutic parameters of the infusion pump based on the capacity of the collapsible fluid reservoir,

wherein determining and setting one or more therapeutic parameters of the infusion pump based on the capacity of the collapsible fluid reservoir determines and sets parameters at lower values for reservoirs having lower capacities and at higher values for reservoirs having higher capacities.

2. The method of claim 1, wherein setting a therapeutic parameter includes setting a basal rate range.

3. The method of claim 1, wherein setting a therapeutic parameter includes setting a bolus volume range.

4. The method of claim 1, wherein setting a therapeutic parameter includes setting a maximum bolus volume range.

5. The method of claim 1, wherein setting a therapeutic parameter includes setting an insulin sensitivity.

6. The method of claim 1, wherein obtaining data on the capacity of the collapsible fluid reservoir includes illuminating optical indicia on the infusion cartridge.

7. The method of claim 6, further including reading an optical code on the infusion cartridge that indicates the capacity of the collapsible fluid reservoir with an optical sensor.

8. The method of claim 7, wherein the optical code on the infusion cartridge is obtained from omnidirectionally reflecting stripes.

9. The method of claim 7, wherein the optical code on the infusion cartridge is obtained from unidirectionally reflecting stripes.

10. The method of claim 6, further including reading a bar code on the infusion cartridge.

11. The method of claim 6, further including reading a quick response code on the infusion cartridge.

12. The method of claim 1, wherein obtaining data on the capacity of the collapsible fluid reservoir includes sensing positions of a plurality of switches coupled to mechanical sensors of the infusion pump that are registered with surface grooves on the infusion cartridge indicating the capacity of the collapsible fluid reservoir.

13. The method of claim 1, wherein obtaining data on the capacity of the collapsible fluid reservoir includes a reading of a radio-frequency identification (RFID) tag affixed on the infusion cartridge, the RFID tag adapted to store data regarding the capacity of the collapsible fluid reservoir.

14. The method of claim 13, wherein a reading of the RFID tag is performed by an RFID reader, which is external to the infusion pump.

15. The method of claim 14, wherein the reading of the RFID reader is wirelessly communicated to the infusion pump.

16. The method of claim 13, wherein the reading of the RFID tag is performed by an RFID reader, which is secured to the infusion pump.
